Effect of particle size distribution on recovery of coarse

The flotation recovery by particle size of single mineral chalcopyrite and galena was studied in a Denver flotation cell, using sodium dicresylthiophosphate (DTP) and sodium isopropyl xanthate (SIPX) as collectors and polypropylene glycol (PPG) as a frother. The study was extended to very coarse particle size (up to 1·6 mm).

Two main approaches are used to improve the fine particle recovery in flotation; to increase the particle size, or to decrease the bubble size. Particle size is increased through several aggregation methods and the aggregated particles are then floated, a process known as floc flotation.
